Glucose tolerance test for pregnant women: Glucose tolerance test, also known as glucose tolerance test, is a laboratory test to diagnose diabetes, called OGTT (Oralglucosetolerancetest, also known as oral glucose tolerance test).OGTT, on the other hand, is the most common clinical test. The OGTT is used in obstetrics to diagnose whether a pregnant woman has gestational diabetes mellitus (GDM), and is an important test during pregnancy to assess a pregnant woman’s blood sugar. Caution: 1. 3 days before the test, ensure a regular diet, do not overeat or intentionally diet. You should not eat after 9:00 pm the day before the test. Prepare a glass of water and 100 – 200 ml of cool plain water in advance on the day of the visit. 2. The approach taken is to take 75g of glucose orally. One 50% glucose is 20ml, and 8 sticks are received at once. Take 7 and a half sticks orally and throw away the remaining half sticks. 3, Note: This test does not need to be booked in advance, the day you are ready to do OGTT must be early to the hospital, strive to 9:00 to be seen (followed by taking medication and blood draws), too late to come. If you can’t make it on the same day, you can take the medication first, get the labs, and do it the next day. Specific steps: Step 1, get the medication: office visit, visit card to prescribe glucose (some hospitals prepare the appropriate sugar water at the nurses’ station in advance) and blood draw labs. Go to the pharmacy to get the medication, 8 sticks of 50% glucose, 20 ml each. Step 2, fasting blood draw: pick up the medication, do not take the medication orally for the time being, go to the blood draw center, first draw fasting venous blood and measure fasting blood glucose. Step 3, oral glucose: 8 sticks of glucose, pour seven and a half of them into a glass of water and take them orally within 5 minutes. If you are thirsty, you can drink a little bit of water. Step 4, draw blood phlebotomy: From the point of oral glucose in step 3, draw fasting venous blood once in the first hour and once in the second hour. For example, if you start oral glucose at 9:10 and drink it within 5 minutes, then draw venous blood once at 10:10 and once at 11:10 to measure blood glucose. Note: From the start of oral glucose, you should not eat anything.
